the obama administration, obama during the campaign has been open about his desire to try to engage iran bilaterally. it is often portrayed as a last ditch effort at diplomacy before you have to resort to other options. with a bilateral negotiation, were that to ever come about, give the u.s. an opportunity to engage on human rights issues? the general policy has been the u.s. wants to keep it limited to large control but is that proper or would there be an opportunity, a window for the u.s. to engage with iran on these issues? >> there has always been a conceptual dispute. there is a group that suggests that the agenda should be kept narrow because otherwise, it gives the iranians the opportunity to divert and talk about afghanistan or by iran or syria. they say the agenda has to remain narrow as a means of focusing issue on our principal concern which is proliferation. the second school of thought suggests if the agenda is broader, perhaps you can have agreements on other issues that would mitigate the agreements on the nuclear issue. that particular concept has never been resolved. wh
